The PC851XPJ000F optoisolator is part of the Transistor, Photovoltaic Output family of optoisolators. PC851XPJ000F optoisolators are designed to provide electrical isolation, signal switching, and protection from high voltage transients in industrial and communications systems. The primary purpose of optoisolators is to safeguard electronic equipment from signaling voltages and to isolate the system from potential damaging current transients. This optoisolator also provides excellent immunity against crosstalk.

The PC851XPJ000F uses an infrared light-emitting diode (LED) and a NPN photo transistor coupled together by a single lens. When the LED is energized, it emits light and activates the NPN photo transistor. The photo transistor is switched on and off, allowing clean, reliable isolation of the input and output signals. The advantage of using an optoisolator is that it allows information to pass between two circuits at a high (optical) frequency, while still providing complete electrical isolation.

The PC851XPJ000F is ideally suited for applications requiring the electrical isolation of DC-input logic signals and driver circuits. Typical applications include motor and solenoid control, pressure and flow sensors, thermistors, and industrial equipment. The PC851XPJ000F optoisolator can also be used to replace relays, mechanical switches, and electromechanical devices in a variety of industrial control systems.

The PC851XPJ000F has a typical operating voltage of 5V DC. The electrical input is converted to an optical signal, which is then converted back to a DC signal when it reaches the output of the optoisolator. The PC851XPJ000F offers an isolation voltage rating of 5000 Vrms, making it well suited for protecting sensitive electronic systems. The optoisolator also offers high gain, wide bandwidth, low operating current, and high isolation levels between the input and output.

The PC851XPJ000F is a robust optoisolator with a wide range of applications. It offers excellent electrical isolation between signal lines, low crosstalk, and low power consumption. It also offers excellent signal transmission characteristics, making it ideal for applications that require high levels of electrical isolation.

The PC851XPJ000F optoisolator is a reliable and cost effective solution for providing electrical isolation. It is designed to offer high levels of electrical isolation, noise rejection, and driver protection in a wide variety of applications. It is suitable for use in industrial and communications systems, making it a popular choice for designers seeking reliable, low cost solutions for signal isolation problems.
